  • Publication number: 20070012494
    Abstract: A method for controlling the drive power distribution in a motor vehicle with hybrid drive by controlling the drive power distribution of torques of an internal combustion engine and an electric motor on a common drive train of a motor vehicle with hybrid drive. The conversion of a reference moment to an actual moment takes place almost without delay, in the case of a load point shift and/or in the case of a change in the moment desired by the driver. The delay in the conversion of reference moments into actual moments is calculated in advance by means of a control device, and the electric motor is controlled by the control device in such a manner that the torque differences that occur due to the delay of the internal combustion engine are balanced out by the electric motor.

  • Patent number: 6895911
    Abstract: A method for simultaneously adjusting camshafts of different cylinder banks of an internal combustion engine to a predetermined nominal angle relative to a crankshaft, where the camshafts actuate associated intake or exhaust valves of the corresponding cylinder banks of the internal combustion engine. The method includes the steps of: detecting a difference in adjusting speeds of associated actual angles of the camshafts, and changing over the time nominal angle of at least one of the camshafts with a higher adjusting speed until the actual angles of the camshafts have reached the original nominal angle. The nominal angle for the camshaft with the higher adjusting speed is changed over time so that a divergence between the actual angles of the camshaft with the higher adjusting speed and the actual angles of the camshaft with the lowest adjusting speed is first stopped and a then corresponding difference between these actual angles is reduced.
